Waterfall Methodologies are considered antiquated in the modern software development landscape, where iterative and agile approaches such as SCRUM, Crystal, eXtreme, Kanban, and NoSQL databases like Couchbase have become commonplace. The author finds that using Couchbase allows for schema flexibility, enabling easy addition or removal of fields without the need for migrations, which reduces headache and makes development smoother. With Couchbase's JSON document storage, developers can easily modify data structures without having to perform migrations, much like creating or consuming an API with JSON. This approach has made development more organic and efficient for the author, particularly when paired with a language like Ruby and a framework like Rails.
